GEORGE r1. BLISS, or nos'roiv, MASSACHUSETTS,,ASSIGNOB To A. GQ RADIS a: SON.

INCL, or BOSTON, MASSACHUSETTS, A oonronn rrolv or MASSACHUSETTS.

oovnn-snounnve Hoop.

T0 allwhomz'tmay concern.

Be it known that I, GEORGE H. BLISS, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and use-' ful Improvements in Cover-SecuringHoops, of which the following is a specification.

This invention relates to means for detachably securing a cover to the upper end f of a receptacle, such as a butter tub, and is.

bead, forming a downhold, adapted to bear on the marginal portion of the receptacle cover, the hoop being of the improved construction hereinafter described and claimed.

Fig. 5 is an edgeview of a portion of the,

hoop in the condition shown by Fig. 2.

Fig. 6- is a side view of the strip or blank from which the hoop is made, the central portion being broken away.

Fig. 7 is a fragmentary perspective vlew, showing a modification.

The same reference characters indicate the same parts in all of the figures.

In carrying out my invention, I form from sheet steel, or other suitable sheet metal, an elongated strip or blank, substantially as shown by Fig. 6, and convert the same by suitable operations, into a coversecuring hoop, a sectional view of which is shown by Fig. 2. Joint-forming end portions 12 and 13, of the strip, are overlapped and united as by rivets 14:, to form a joint which is narrower than the maximum width of the strip. As shown by Figs. 2, 4:, 5 and 6, the end portion 12 is relatively narrow, and the end portion 13 has the full width of the strip. As shown by Fig. 7 both end portions are narrower than the body of the specific-men of Letters Patent.

. Strip, a relatively narrow portion 13 being substituted for the portion 13, the arrangement being such that, in either case the joint is narrower than the maximum width of the hoop, and the hoop has two opposed edge portlons 15, which are located above. the

joint,'and areseparated by a crevice.

The lower edge portion of the hoop below the dotted line 16, constitutes a continuous receptacle embracing lower zone which includes the said joint. The upper edge portion of the hoop, above the line 16, is dis-' continuous, and constitutes a bead-forming upper zone which includes the opposed edge portions 15.

Said discontinuous upper zone is rolled inwardly, to form a discontinuous hollow bead 18, the continuity of which is interrupted by said crevice, the edge portions 15 forming the opposed ends of the head. The 'width of the bead-forming zone is such that the bead'is entirely above the joint formed by the portions 12 and 13. The head 18 is therefore composed of a Single thickness of sheet metal from end to end, and, owing to the fact that it is entirely above the hoop joint, is adapted to be easily produced by suitable bead-forming appliances, after the joint is formed, there being no contact of any of the portions of the strip from which the bead is formed, with the joint portion of V the hoop, and,,therefore, no greater resistance to the formation of the bead at the joint portion of the hoop than elsewhere.

The lower zone of the hoop, below the dotted line 16, is formed to bear on the body 20, and onthe margin of the cover 21 of a receptacle, such as a butter'tub, and is provided with holes 22, to receive attaching nails 23. The bead 18 is formed to bear as a downhold, on the marginal portion of the cover. The heads of thenails 23 may be formed to be engaged and withdrawn by a pulling device, to permit the removal of the hoop and cover.

It is obvious, that the hoop, when in the condition shown by Fig. 1, may be headed of the periphery of a circular receptacle and secure a cover thereto, said hoop being formed from an elongated sheet metal strip having overlapping joint-forming portions 13 at its opposite ends, said portlons overlapping and being united to form a joint which is narrower than the maximum width of the strip, so that the hoop has a'continuous receptacle-embraeing lower zone including said joint, and a bead-forming upper being rolled inward after the formation of said joint to form a cover-securing head, located entirely above said joint.

In testimony whereof I have afiixed my 1 signature. 1
